I agree with some of the statements of the blog. However it misses one important point in how people use lists. For example I follow around 300 people, some of them are very noisy some times but eventually they post something interesting, so I feel that the noisy is an acceptable price to pay.
Nevertheless, because of the overflow of information, many times I miss posts of quiet people that generally have something important to say. Then, lists come to the rescue.
I just put those very interesting people in a list that I can check for time to time. If people follow my list(s), they give the authority that I created it(them)or whatever I do not really care. For me that is just marketing trying to convince of the value of twitter. For me, the value is finding good content with less effort; and I think the lists are helping on it.<p>Note: I use also tweetdeck that has a similar concept, which I found very useful. Perhaps that is why I liked the lists concept.
